“…There have been prior experiences using zein materials for food packaging [ 44 ]. According to Visakh [ 45 ], the proteins isolated from soybeans can also be used to create edible films, which are frequently created through baking or casting techniques [ 46 ]. Despite their stretchability and good mechanical properties, soy proteins rarely function as water barriers [ 47 ].…”

Food packaging was not as important in the past as it is now, because the world has more people but fewer food resources. Food packaging will become more prevalent and go from being a nice-to-have to an essential feature of modern life. Food packaging has grown to be an important industry sector in today’s world of more people and more food. Food packaging innovation faces significant challenges in extending perishable food products’ shelf life and contributing to meeting daily nutrient requirements as people nowadays are searching for foods that offer additional health advantages. Modern food preservation techniques have two objectives: process viability and safe, environmentally friendly end products. Long-term storage techniques can include the use of edible coatings and films. This article gives a succinct overview of the supplies and procedures used to coat food products with conventional packaging films and coatings. The key findings summarizing the biodegradable packaging materials are emphasized for their ability to prolong the freshness and flavor of a wide range of food items; films and edible coatings are highlighted as viable alternatives to traditional packaging methods. We discuss the safety concerns and opportunities presented by applying edible films and coatings, allowing it to be used as quality indicators for time-sensitive foods.

“…Both lignin-based polymers are the starting material for composites ( Glasser, 2016 ), bio-based nanomaterials ( Grossman and Vermerris, 2019 ), and carbon fibers ( Wei and Oksman, 2022 ). b) Polymers from biomonomers: Monomers from renewable sources that are used in polymer chemistry are commonly referred to as biomonomers ( Visakh, 2019 ). The polymers can be synthesized from a single difunctional biomonomer molecule such as dialcohols to give polyethers, or from hydroxy acids to give polyesters.…”

Climate change, socioeconomical pressures, and new policy and legislation are driving a decarbonization process across industries, with a critical shift from a fossil-based economy toward a biomass-based one. This new paradigm implies not only a gradual phasing out of fossil fuels as a source of energy but also a move away from crude oil as a source of platform chemicals, polymers, drugs, solvents and many other critical materials, and consumer goods that are ubiquitous in our everyday life. If we are to achieve the United Nations’ Sustainable Development Goals, crude oil must be substituted by renewable sources, and in this evolution, biorefineries arise as the critical alternative to traditional refineries for producing fuels, chemical building blocks, and materials out of non-edible biomass and biomass waste. State-of-the-art biorefineries already produce cost-competitive chemicals and materials, but other products remain challenging from the economic point of view, or their scaled-up production processes are still not sufficiently developed. In particular, lignin’s depolymerization is a required milestone for the success of integrated biorefineries, and better catalysts and processes must be improved to prepare bio-based aromatic simple molecules. This review summarizes current challenges in biorefinery systems, while it suggests possible directions and goals for sustainable development in the years to come.

“…Polymer blends based on thermoplastic biopolymers (e.g., thermoplastic starch) have been developed, 106 along with biopolymer composites, 107 thermoplastic polyurethanes with biodegradable segments, 108 and other multiblock thermoplastic materials based on natural monomers. 109 However, these would display some of the limitations related to bioadhesives.…”

Adhesive Interfaces toward a Zero-Waste Industry

This Feature Article evaluates ongoing efforts to adapt adhesives toward the goal of zero-waste living and suggests the most promising future directions. Adhesives are not always considered in zero-waste manufacturing because they represent only a small fraction of a product and offer no additional functionality. However, their presence restricts the reintegration of constituent parts into a circular economy, so a new generation of adhesives is required. Furthermore, their production often leads to harmful pollutants. Here, two main approaches toward addressing these problems are considered: first, the use of natural materials that replace petroleum-based polymers from which conventional adhesives are made and second, the production of dismantlable adhesives capable of debonding on demand with the application of an external stimulus. These approaches, either individually or combined, offer a new paradigm in zero-waste industrial production and consumer applications.
